The present invention relates to a biodegradable magnesium alloy and a biodegradable implant using same, wherein the magnesium alloy comprises 0.5 weight% (inclusive) to 3.0 weight% (exclusive) of Zn; 0.0 weight% (inclusive) to 2.0 weight% (inclusive) of Mn; 0.0 weight% (inclusive) to 3.0 weight% (exclusive) of Sr; 0.0 weight% (inclusive) to 2.0 weight% (inclusive) of Ca; and the balance of Mg. According to the composition, there is an advantage of improving the strength and corrosive resistance of the biodegradable magnesium alloy. La présente invention concerne un alliage de magnésium biodégradable, ainsi qu'un implant biodégradable l'utilisant, l'alliage de magnésium comprenant : de 0,5 % en poids (inclus) à 3,0 % en poids (exclu) de Zn ; de 0,0 % en poids (inclus) à 2,0 % en poids (inclus) de Mn ; de 0,0 % en poids (inclus) à 3,0 % en poids (exclu) de Sr ; de 0,0 % en poids (inclus) à 2,0 % en poids (inclus) de Ca ; le reste étant constitué de Mg. Selon la composition, il est avantageux d'améliorer la résistance et la résistance à la corrosion de l'alliage de magnésium biodégradable. 본 발명은 마그네슘 합금 총 중량에 대하여, 0.5 중량% 이상 3.0 중량% 미만의 Zn; 0.0 중량% 이상 2.0 중량% 이하의 Mn; 0.0 중량% 이상 3.0 중량% 미만의 Sr; 0.0 중량% 이상 2.0 중량% 이하의 Ca; 및 잔량의 Mg을 포함하는, 생분해성 마그네슘 합금 및 이를 이용한 생분해성 임플란트에 관한 것이다. 상기한 구성에 의하면, 생분해성 마그네슘 합금의 강도 및 내식성을 동시에 향상시킬 수 있는 이점이 있다.
